The SKF TNH/HC series deep groove ball bearing is a single row bearing with a polyamide cage and C3 internal clearance, designed for applications requiring higher speed and lower heat generation. Its design handles moderate radial and axial loads in both directions. MR Accesorios Industriales supplies this line with technical support to select the right variant for your equipment.
The designation of this series combines letters and numbers that indicate specific features. For example, in 6305 TNH/HC5C3, the numeric prefix identifies the size and dimension series; TNH indicates a glass fiber reinforced polyamide cage, suitable for high temperatures; HC5 indicates ceramic rolling elements, and C3 defines a greater than standard internal radial clearance. Understanding these suffixes is key to ordering the correct bearing.
These bearings are used in industries such as food, chemical, pharmaceutical and process industries, where high speeds and moderate temperatures demand reliable solutions. They also appear in electric motors, pumps, fans and transmission equipment. In Argentina, they are commonly found in production lines that require low maintenance. MR Accesorios Industriales supplies them throughout the country.
To select the right bearing, consider radial and axial load, rotational speed and operating temperature. The TNH cage withstands high temperatures better than standard polyamide cages. C3 clearance is recommended when there are interference fits or thermal gradients. Mounting must be done with suitable tools, avoiding direct impacts, and lubrication must be as specified by the manufacturer to ensure long service life.
Regarding equivalents, other manufacturers offer bearings with similar features, but part numbers may vary. Always verify critical dimensions and operating conditions before replacing one bearing with another brand. Interchangeability is not automatic: the same size may have different clearance, cage or material. Contact us if you need help finding the correct replacement.

Frequently Asked Questions
- What are the dimensions of the SKF 6305 TNH/HC5C3 bearing?
- The SKF 6305 TNH/HC5C3 bearing has a 25 mm bore, a 62 mm outside diameter and a 17 mm width (25 x 62 x 17 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6305.
- What does the TNH suffix mean on this bearing?
- TNH indicates a glass fiber reinforced polyamide cage, designed to withstand higher temperatures than conventional polyamide cages. It is a common option in applications where heat is a critical factor.
- When is C3 clearance preferable to standard?
- C3 clearance is recommended when the bearing operates with interference fits on the shaft or housing, or when there are thermal differences between the inner and outer rings. This prevents the clearance from becoming too small and causing overloads.
- Can I replace this bearing with one from another brand?
- Yes, but verify that the main dimensions, internal clearance, cage type and rolling element material match. Not all equivalent part numbers are identical. If in doubt, contact us with the original part number.
